That seems pretty reasonable. If it is urgent-someone could be seriously hurt and the OC liable-the EC can and should spend the money to fix the problem immediately. Even if someone won’t get hurt but the OC is likely to be exposed to some other serious liability the EC should get on with fixing the problem and sort out who should have paid later. If it is not urgent, non-trivial amounts of unbudgeted spending should wait to go on an agenda for approval from a general meeting.
